在本文为主要介绍DLA服务关联角色（AliyunServiceRoleForOpenAnalytics）的应用场景以及如何删除服务关联角色。

背景信息

DLA服务关联角色（AliyunServiceRoleForOpenAnalytics）是在某些情况下，为了完成DLA自身的某个功能，需要获取其他各种各样的云服务的访问权限，而提供的RAM角色。更多信息请参见服务关联角色。

应用场景

DLA作为阿里云数据湖分析产品，提供Serverless Presto和Spark的核心产品功能，需要为用户打通、连接、关联各种各样的阿里云数据源和各种云服务产品（OSS、OTS、RDS、ADS、ODPS、ECS、VPC、RAM、MQ等），从而实现数据湖的各种各样的功能。因此，DLA会在用户开通DLA服务的时候，自动化的帮助用户在DLA内部创建好服务关联角色，从而极大的提高用户体验。

删除服务关联角色

当您尝试删除服务关联角色（AliyunServiceRoleForOpenAnalytics）时，您需要进行如下操作：
  • 关闭当前Region和其他所有Region的DLA服务，因为DLA是以用户账号维度来判断SLR的关联性。
  • 删除服务关联角色，具体操作请参见服务关联角色。
